With the three-year Broadway Corridor project in Forest Lake aiming for a September completion, the Washington County Board received an update on costs and contracts on June 12. The project runs from just west of I-35 to just west of US-61, and includes grading, concrete and bituminous paving, storm sewer, concrete curb and gutter, traffic signals, signing and striping, lighting, water main, sanitary sewer and a bridge over the interstate.
In 2011, the board approved a pilot contract program for the project that changes the threshold at which the board must approve construction contract amendments. The budget is $16.4 million for the interchange and roadway construction. Unexpected changes during construction included finding extra debris in roadbeds and drainage ponds, finding asbestos in road debris, power pole relocation delays, and a need for additional muck excavation and fill for the interchange and bridge. Contract changes processed to date total $955,966.21.
In addition, costs not included in the 7 percent contingency include money for erosion control, costs incurred by last year’s state government shutdown, and additional streetscaping, the latter of which will cost an additional $511,000.
